摘要：
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) Fe2O3 using high-energy ball mill. The products are characterized by X-ray powder diffraction technique. Influence of milling conditions: milling time from 5 min to 10 h, milling medium (steel or ZrO2) and injected mechanical power on unit-cell parameters and crystallinity of products, as well as on reaction kinetics are investigated and discussed.
